TFT 2.2 インチ液晶ディスプレイモジュール 240 X 320 MCU 標準ST7789V2-G4

The COB LCD module is compact and easy to integrate into my custom PCB. I like that it supports standard ASCII characters, which makes displaying status messages simple. The LED backlight is uniform across the screen, and I haven't noticed any dead pixels. Would recommend for hobbyists and professionals alike.

I used this OLED in my project, the COG structure saves space and doesn't require a backlight. ssd1315 driver is stable, interface compatibility is good, the information is complete, and the development is smooth. The only thing I need to pay attention to is the 7.25V display power supply, but the overall experience is very good.

Excellent clarity, great for pro projects, minor library quirks.I used this for a custom CNC controller box, and the screen is fantastically bright—way better than the typical 20-30cd/m² modules. The full-viewing angle means the operator can see it from any position. The I2C interface saved me precious GPIO pins on my microcontroller. It was plug-and-play with common Arduino libraries, though I had to tweak the contrast setting significantly to get the best look with that high brightness. For the price, the build quality feels solid. One less star only because the documentation was a bit sparse, but if you're familiar with I2C displays, you'll be up and running in minutes. Incredible value for a high-brightness module.
